TPWS question--2020 Camry XSE
Hi All,
My dad recently bought a new 2020 XSE. Great car---he loves it. I've been helping him learn the controls/settings etc. In the settings menu on Multi Information Display I went into the TPWS control and mistakenly clicked "set pressure" and "ok" on the TPMS. The TPMS indicator blinked and then stayed solid. I guess I reset/recalibrated it. I turned the car off and then restarted it and the warning light was gone. I went back into the same settings to see if I could have changed the "threshold" for when the sensor alerts the driver when the pressure is low (can that even be changed?). I then clicked "change wheel" thinking that might help but I ended up resetting/recalibrating again. Eventually, the warning light went out and after driving about 5 minutes I was able to see the PSI for each tire in the display. Questions: 1. Did I inadvertently change anything that I need to go back in and correct? (the car is brand new---less than a week) 2. Is the threshold for when the warning light comes set by me or within the sensor (by the dealer) Thanks for taking the time to read! John |
When resetting, make sure all tires are at the desired pressure and have the same pressure. A reset changes the established PSI setting.
Not sure how much tire pressure PSI drop or pressure variance is OK between tires before a warming is triggered. Guessing at least 5 psi. |
Thank you! After making sure each tire is at the same pressure should I go into the setting and choose “set pressure”? Do I need to do anything with the “change tire” setting?

If the system is working now would not do anything.
If it has problems again make sure tire pressures are the same and do a reset. |
Great. Thanks so much.
